not to hop on this guy's thread but a short squeeze is when you short a stock and the price keeps going up. The idea is the "shorts" get squeezed out of their position. Hope that helps.

Thanks for the explanation. I do actually know what a short squeeze is, I'm hoping I can get an explanation of how one can determine it's happening - either through Time and Sales or through Level 2 (if that is what is used).

@devask168 It's more about knowing when shorts are trapped after a large spike and drop whether intraday or after several days. I personally use level 2 and the charts but when something is spiking huge without a catalyst, typically its a short squeeze
